This paper examines the relationship between idiosyncratic risk and stock returns in BRICS (Brazil, Russia, India, China, and South Africa) countries by applying parametric and nonparametric approaches. It also explores the idiosyncratic risk puzzle by dividing firms into groups based on...

We investigate the relationship between changing correlation structure of returns, security risk, and mean return. According to our results, securities that were highly correlated with the market-wide risk factors in the past are likely to have high systematic and idiosyncratic risk at present....

This paper aims to examine the relation between idiosyncratic volatility (IVOL) and stock returns with full-sample and conditional alpha sub-samples in Vietnam stock market covering the period from January 2008 to December 2018. We test the IVOL effect on stock returns employing Fama-Macbeth...

We examine the roles of rational and behavioural factors in explaining long-run premiums/discounts on closed-end funds, using evidence on equity funds from the US and UK. Although the processes by which fund prices converge towards long-run premiums or discounts are similar in the two countries,...

Many papers claim that value and size fundamentals (book-to-price ratios and market capitalization) yield positive expected return premia because they are proxies for systematic risk factors in conditional and/or multi-factor CAPM. Much of empirical evidence to support this idea comes from...

This paper examines the time-series predictability of aggregate stock returns in 20 emerging markets. In contrast to the aggregate-level findings in US, earnings yield forecasts the time-series of aggregate stock returns in emerging markets. We consider aggregate earnings not as normalizing...

This paper investigates whether realized and implied volatilities of individual stocks can predict the cross-sectional variation in expected returns. Although the levels of volatilities from the physical and risk-neutral distributions cannot predict future returns, there is a significant...

CAPM has come a long way, has passed the time-test, and is fast coming out as a winner despite the onslaught of both, APT and multi-factor CAPM. The bottom line is that CAPM is needed, dead or alive. If so, it does not mean that CAPM stays as, “CAPM." Downside risk in recent times has caught...

The Capital Asset Pricing Model allows to price risky financial assets, in seductive simple way, but under various theoretical assumptions. Since its inception, CAPM has been questioned due to some of its unrealistic theoretical assumption or due to its empirical failures. Academicians have been...
